Sgt. Confessor Gonzalez plans to contact Montreal police to explore possible links between Magnotta and the mysterious, 2009 death and dismemberment of Guatemalan national Omar Laparra.
Miami police say Laparra, 21, vanished after leaving a bar in Miami's Little Havana neighbourhood early in the morning on May 31, 2009. He was never seen alive again.
Over the following several days, Gonzalez said Laparra's remains were found stuffed in four plastic bags floating in waterways around the southern part of the city.
"We were never able to put it together," he said about the case, which was described by U.S. TV show America's Most Wanted..."
